10/28/2016 | 1) Prior to starting repair work a bradenhead test shall be performed. If any pressure remains at the conclusion of the test or any liquids were present contact COGCC Engineer for sampling requirements before pumping any cement. The Form 17 shall be submitted within 10 days of the test.
2) The additional cement referenced shall be placed as indicated. The placed cement shall be verified with a CBL and documented with a Form 5.

2/2/2018 | Plugging
• Provide 48 hour notice of plugging MIRU via electronic Form 42.
• If there is fluid migration or shut-in pressure on the well prior to pumping any plug(annular or casing) that isolates deepest aquifer or the surface casing shoe (whichever is deeper) contact COGCC Engineer for revised plugging orders.
• If the shoe plug, or combined stub/shoe plug, is not circulated to the surface then the plug shall be tagged and must be 50’ into the shoe, or 50’ above the cut, whichever is shallower.
• Place a 50' plug(minimum) at the surface, all other plugs shall have at least 100' of cement left in the casing.
• Properly abandon flowlines as per Rule 1103. |

2/2/2018 | Bradenhead Testing
Prior to starting plugging operations, a bradenhead test shall be performed. If the initial
shut-in bradenhead pressure is greater than 25 psi or liquid is present at any time
during the test, sampling is required. Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions, Appendix A: Liquid and Gas Sampling. |
